Metabolic impact of protein feeding prior to moderate-intensity treadmill exercise in a fasted state: a pilot study

Table 1 Effect size calculations

Relative Energy Expenditure (kcal/kg/day)
	Effect Size Within-Group	Effect Size (Nutrient vs. CON)	Effect Size (Nutrient vs. MAL)
WPI	1.15	0.91	1.36
CAS	1.32	1.15	2.00
MAL	0.63	− 0.28	–
CON	0.74	–	0.28
Respiratory Exchange Ratio
	Effect Size Within-Group	Effect Size (Nutrient vs. CON)	Effect Size (Nutrient vs. MAL)
WPI	−0.77	−0.65	−0.97
CAS	−0.41	− 0.56	−1.04

WPI = Whey protein isolate; CAS = Casein; MAL = Maltodextrin; CON = Control. Effect size within-group = (post-exercise – pre-exercise) / pooled SD. Effect Size (Nutrient vs. CON) = Post-delta – Pre delta / pooled SD. Effect Size (Nutrient vs. MAL) = Post-delta – Pre-delta / pooled SD
